Product Description

While some folks might look at the number 13 as a bit unlucky, here at Chain Reaction Bicycles, we're not too superstitious, which is why we won't hesitate to hop upon our trusty steeds with ROTOR's exclusive 1x13 groupset. This sleek grouppo offers seamless shifting, and a sequential gear range that accommodates all kinds of cyclists in all kinds of situations.

This is achieved with a 1x13 single chainring hydraulic system that keeps weight at a minimum, while prioritizing aerodynamics for a reliable solution that lets you focus on your pedaling rhythm as you hammer up treacherous mountain roads, instead of worrying about exactly where to make that pesky front-derailleur shift.

1x13 is designed with all disciplines in mind, with cassettes crafted to offer ranges that appease road, gravel, and cyclocross riders alike, so you can pick the combination that best suits your needs, whether your goal is to hit the highest speeds on the peloton, or have the biggest bailout cog for steep fire roads when you're chasing wily DH descents. We achieve this flexibility thanks to the near perfect sequencing of gears, and a robust derailleur that can handle any terrain.

Our 1x13 Adventure Kit is built for the free-spirited cyclist who wants to lace things up just the way they want, chasing down horizons from the roughest of gravel grinds, to the peloton. This kit enables you to pick your own hoops, and dial your drivetrain just how you want it, with RVOLVER 1x13 hubs, the 13-speed cassette of your choice, shifters, derailleur, cables, chain, and last, but certainly not least, our sleek ALDHU crankset that keeps weight to a minimum, while holding on to the stiffness you need to conquer the road less traveled.

Lightweight & Robust

With fewer components on board, ROTOR 1x13 slims down to featherweight scaling, while benefitting from maximum rigidity and optimal structural efficiency from modern disc brake systems. It features cutting edge Spanish CNC manufacturing to strike the perfect balance between lightness, precision, and durability.

Switching things up from the mechanical groupset you know well, the 1x13 is designed with indexing located in the rear derailleur, as opposed to shifters, which helps deliver its crisp, precise shifting inside of the robust casing. By locating the component weight in the back we're able to better distribute weight, and add more natural balance and stability to your ride. And in case you get a little wild on the road or trail, the 1x13 derailleur is protected by our reinforced Armored Box that protects against all external elements, shocks, and impacts.
